biome migrate eslint now correctly resolves scoped package named eslint-config with a path.
Contributed by @Conaclos
biome migrate eslint now correctly handles shared ESLint configuration that don't follow the ESLint naming convention (#4528).
ESLint recommends that a package that exports a shared configuration be prefixed with eslint-config- or simply named eslint-config.
This is only a recommendation.
Packages that export shared configurations can have arbitrary names.
Biome is now able to load any package.

useFilenamingConvention accepts a new option match (#4105).
You can now validate filenames with a regular expression.
For instance, you can allow filenames to start with %:
```
{
  "linter": {
    "rules": {
      "style": {
        "useFilenamingConvention": {
          "level": "warn",
          "options": {
              "match": "%?(.+?)[.](.+)",
              "filenameCases": ["camelCase"]
          }
        }
      }
    }
  }
}
```
If the regular expression captures strings, the first capture is considered to be the name of the file, and the second one to be the extensions (dot-separated values).
The name of the file and the extensions are checked against filenameCases.
Given the previous configuration, the filename %index.d.ts is valid because the first capture index is in camelCase and the second capture d.ts include dot-separated values in lowercase.
On the other hand, %Index.d.ts is not valid because the first capture Index is in PascalCase.
Note that specifying match disallows any exceptions that are handled by the rule by default.
For example, the previous configuration doesn't allow filenames to be prefixed with underscores,
a period or a plus sign.
You need to include them in the regular expression if you still want to allow these exceptions.
Contributed by @Conaclos
useFilenamingConvention and useNamingConvention match options now accept case-insensitive and case-sensitive groups.
By default, the regular expression in match is case-sensitive.
You can now make it case-insensitive by using a case-insensitive group (?i:).
For example, the regular expression (?i:a) matches a and A.

noUndeclaredVariables now provides the checkTypes option (#3998).
noUndeclaredVariables is inspired by the no-undef ESLint rule. It reports all references that are not bound to any declarations within a module.
Node.js, JavaScript and TypeScript globals are ignored.
Biome provides the javascript.globals option to list additional globals that should be ignored by the rule.
In TypeScript projects, developers often use global declaration files to declare global types.
Biome is currently unable to detect these global types.
This creates many false positives for noUndeclaredVariables.
TypeScript is better suited to perform this kind of check.
As proof of this, TypeScript ESLint doesn't provide any rule that extends the no-undef ESLint rule.
This is why we introduce today a new option checkTypes which, when it is set to false, ignores undeclared type references.
Given the following configuration...
```
{
    "linter": {
        "rules": {
            "correctness": {
                "noUndeclaredVariables": {
                    "level": "error",
                    "options": { "checkTypes": false }
                }
            }
        }
    }
}
```
... UndeclaredType is not reported by the rule.
```
export default function(): UndeclaredType {}
```
We plan to turn off the option by default in Biome 2.0
Also, this will bring the Biome rule closer to the no-undef ESLint rule.

Enhancements

useExportType and useImportType now ignore TypeScript declaration files (#4416). Contributed by @Conaclos
useArrayLiterals now provides a code fix.
```
- const xs = new Array();
+ const xs = [];
```
The code fix is currently marked as unsafe.
We plan to make it safe in a future release of Biome.

noUnusedImports now reports empty named imports and suggests its removal (#3574).
The rule now suggests the removal of empty named imports such as:
```
- import {} from "mod";
```
Contributed by @Conaclos
noUnusedImports now keeps comments separated from the import with a blank line (#3401).
Here is an example:
```
  // Orphan comment

- // Header comment
- import {} from "mod";
```
Contributed by @Conaclos
useValidTypeof now accepts comparisons with variables.
Previously, the rule required to compare a typeof expression against another typeof expression or a valid string literal.
We now accept more cases, notably comparison against a variable:
```
if (typeof foo === bar) {
  // ...
}
```
Contributed by @Conaclos

noUnknownProperty now accepts more known CSS properties (#4549).

- ['anchor-default', 'anchor-scroll', 'inset-area', 'position-animation', 'position-fallback', 'position-fallback-bounds', 'position-try-options']
+ ['anchor-scope', 'interpolate-size', 'line-fit-edge', 'masonry', 'masonry-auto-tracks', 'masonry-direction', 'masonry-fill', 'masonry-flow', 'masonry-slack', 'masonry-template-areas', 'masonry-template-tracks', 'position-anchor', 'position-area', 'position-try-fallbacks', 'position-visibility', 'scroll-start-target', 'text-box', 'view-transition-class', 'view-transition-group']

This change replaces deprecated properties, improving CSS validation.

Bug fixes

noControlCharactersInRegex no longer panics when it encounters an unterminated unicode escape sequence (#4565). Contributed by @Conaclos
useArrayLiterals now reports all expressions using the Array constructors.
Previously, the rule reported only use of the Array constructor in expressions statements.
```
// This was reported
new Array();
// This was not reported
const xs = new Array();
```
Contributed by @Conaclos
useArrowFunction now preserves directives (#4530).
Previously the rule removed the directives when a function expression was turned into an arrow function.
The rule now correctly keeps the directives.
```
- const withDirective = function () {
+ const withDirective = () => {
      "use server";
      return 0;
  }
```
Contributed by @Conaclos
noUndeclaredVariables is now able to bind read of value to a type-only import in ambient contexts (#4526).
In the following code, A is now correctly bound to the type-only import.
Previously, A was reported as an undeclared variable.
```
import type { A } from "mod";

declare class B extends A {}
```
